Description

Mepronil CAS NO 55814-41-0 is a systemic fungicide belonging to the benzanilide chemical class. It is valued for its protective and curative action against a range of fungal pathogens, particularly those affecting rice crops. This compound is essential for agricultural professionals and agrochemical formulators seeking reliable disease control solutions to protect crop yield and quality.

Application

• Rice Blast Control: Primary application for the prevention and treatment of rice blast disease caused by *Magnaporthe grisea*.
• Agricultural Fungicide Formulations: A key active ingredient in emulsifiable concentrates (EC), wettable powders (WP), and suspension concentrates (SC) for foliar application.
• Crop Protection Programs: Used in integrated pest management (IPM) strategies for rice, and potentially for other cereals.
• Seed Treatment: Applied as a seed dressing to protect seedlings from early-season soil-borne and seed-borne fungal infections.
• Research & Development: Serves as a reference standard or intermediate in agricultural chemical research and for the synthesis of novel fungicidal compounds.
